Thisl invention is for improvements in or relating to machines for winding yarn and the like on cops or bobbinsr. The object of the invention is to enable such a machine to benadjusted easily `and quickly so as to wind cops or bobbins of different diameters, lengths and shapes.

According to the present invention, a winding machine comprises a traverse-rod having an eX- tension on which the progression-wheel' is mounted and means for adjusting the said extension laterally of the traverse-rod whereby the distance between the progression-wheelr and the axis of the winding-spindle may be varied. The'said means may comprise` a pin-and-slot connection, more fully described below, between the traverserod and the said extension and an adjustable bracket for supporting the remote end of the extension. j

According toanother featureofthe invention, the inner end of the said extension is slotted to receive within it a former-bar attached to the outer end of the traverse-rod and zzo-operating with rthe hub of the `progression-wheel so as to build the heel of a cop onfa plain tube. This former-bar takes the place of the usual external bar co-operating with` a projection on the thread guide. 1

According to yet another feature of the invention, cam-mechanism is provided for reciprocating the traverse-bar with a varying speed of movement during each stroke. In this way, a rm non-shattering chase is obtained. 1

A specific embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, in

which: i l

Figures la and lb show a plan of a windingmachine according to the invention with certain parts omitted;

Figures 2a. and 2bI show an elevation` partly in section, of the machine shown in Figure l;

Figure 3 is an elevation looking on the righthand end of Figure 2;

Figure-4 is a section'on the lines'4-4 of ure 1b, and

Figure 5 is a section on thel lines `5--5'of Fig- As shown in the drawings, themachine comprises a main frame vIIlhavng bearings I I fora tubular clutch-memberl I2 and a'spindle I3which lies within it.4 The'tube I2 carriesa groovedwheel I4 which.'r abuts against a spring'IS,` the other end of which engages a collar I6 'afxed to Figthe spindle I3. The worm I1 forms part of a tube which is also aflixed to the spindle I3.

- ARotatably mounted on the left-hand end of the spindle I3 is a pulley I9 having a conical face to co-operate with avclutch-memberlll formed integrally with the tube I2. |lhe outer end of the (Cl.l 242-31) spindle I3 is supported ina bracket 2l (see also lFigure 2).

The right-hand end vof the tube I2 is formed with dogs 22 adapted to engage with corresponding slots in the collar I6 whereby a driving-connection is established between the tube I2. and the collar I6 so that-When the clutch-member 20 is in frictional engagement withthe pulley I9,

rotation of the pulley drives the spindle. The right-hand end of l the Aspindle carries spring-iingers 23 Vto engage the end 24 of a copholder; the other end 25 of the cop being supported by a centering-spindle 26 mounted in bearings in a plunger 21 pressed towards the cop by means of a spring 28 and slidable in a guide 29. The plunger 21 terminates in a knob 30 whereby it may be retracted manually.

The worm I1 (see Figure 2) engages anddrives a worm-wheel 3| having cut in its face acamtrack vof two portions 32 and 33. The track is engaged lby a follower 34 on the shorter arm 35 of a bell-crank lever 35, 36, pivoted to the frame at 31. The arm 36 is pivoted to a link 38 which is in turn pivoted at 39 to a traverse-rod 46 slidable in a tubular guide 4I and in a bush 42.

vThe traverse-rod 40 carries a screw-threaded extension 43 pivotally attached to it as follows: As shown in Figures l, 2 and 4, a former-bar k4K6, more fullydescribed below, has a screw-threaded end 44 which engages the recessed end ofthe traverse-rod 40 and is secured against rotation with respect thereto by a lock-nut 45. The screwthreaded extension 43 ofthe traverse-rod is slotted, as shown in `F igure-2b', the former-bar 46 lying within this slot. vThe heel of the formerbar 46 is cut with a radial slot 41 through which passes. a pin 48 carried on the screw-threaded portion 43. The pin 48 is engaged by a tensionspring 49, the other end of which engages a pillar 56 aixed to a bracket 5I on the former-bar, so as to tend to move the screw-threaded portion downwardly, as seen inFigure l. This tendency is resisted, however, by an adjusting-screw 52 passing through the bracket5l and engaging with the enlarged head-portionf53 of the pin 48.

. The other end of the screw-threadedvrod 43 is mounted in a.universal-joint 54 in a sleeve 55 which is attached by ascrew 56 to a bracket 51 which is an extension from the-main frame I0.

The screw-threaded rod 43carries the usual .progression-wheel 58, the hub 59 of which is freely slidable along it, but which has a resilient wire 60 which passes through a slot in the hub into engagement with .the screw-threads,r so that the progression-wheel normally behaves as lthough it were screw-threaded to the rod 43.

`When it is required to build the `c`op`63 on a 'Mio plain cylindrical tube the parts are arranged as shown in the drawings, the progression-wheel 58 is moved to its extreme left-hand position (the spring 60 being released for this purpose) until` the hub 59 rides along the former-,bar 46 and consequently-pivots the screw-threaded rod 43 about 54, the pin 48 moving along the slotl 4711;? It will be appreciated that the rod 43 now lies at an oblique angle to the traverse-rod axis, ha-v-ingtilted about the joint 54. WithA the periphery ofA the progression-wheel 58 just touching the bare cop-tube the machine is set -inemotion' and winding commences.

Theshape of the cametrack 32, 33 causes the traverserrod to be moved outwards c'omparati'velyV quickly Yowing to the short'and comparatively steep angle of the Vspiralriii', but inwardly at a vmuch"slower'ratel of speed owing to thelong gradual rslopeof the spiral 32. f A further. importatfpoint Vof designin the camtrackris that each portion 32, 33 is somewhat steeper than atrue" Archim'edean spiral, withrthe' a progressive movem'ent'tov the right; Viii/"hereupon anew chase is started.

Y e s, 7' t When the cop hasbee'nfully'built the'p'ro'ission-wheel 58 engages witl'fl'ar bracket 621 carried on a rod 65, with the Aresult that'this rod is moved endwise and rotates aflatcnl; (se-eligureZ 'which normally holds adog 61 attached to` afbar 68. The bar 68 is engaged by a Ispring 69 jat- -tached to a collar AIll4 in suchjmanner astoftend to rotate it inwardlyso that--whenlthe dog B1' is released the bar rotates and the wedge-member II attached to a collar 'I2 on therodenig'ages the groove in the wheel I4, presses this wheel to the right against the lpressure of-'wthesp'ring I jre'f leases tY e cone 28 from the p ulleyvland thusinterrupts the drive. v' 5 In the method of opeauen".d/esened'eudve,

the screw 52 is s'et'so that, after the progression-` wheel 58 parts company'with the former-bar R45 the screw-threaded rod 43 shalljlie co-axialfwith the traverse-rod 46. However, the parts may be 4differently arranged so asto give any desired shape to the heel of the cop. The parts may also be arranged so as to wind'on apirnja pre-formed conical end so as automaticallytowind on the rst sloping chase. This arrangement is achieved as follows:

The spindle I3 isY moved to-the right with re'- spect tothe tubes I2, collar I6, and worm I'I by the release Vof appropriate grub-screws whichare subsequently rel-tightened.` The Vextent of movement is suchas to bringthe point of commence- TheY spindle I3 rotates in the l direction of the arrow shown in Figure 1. with ment of Winding on the pirn opposite a point on the traverse-rod lying beyond the position on which the hub 59 of the progression-wheel parts company fromv the inclined edge of the formerbar 55. VIt will be seen that the diameter of the nished bobbin depends on the distance of'the screw-threaded rod 43 from the axisof the spinellev I3Y andV the present invention enables this distance'to be readily adjusted. First, the screw 52eis adjusted soas to bring the inner endrof the rod 43 to the desired position. If necessary, the nut 45 may belslackened off and the former-bar 46 rotated about its axis for this purpose. Thus, a `.wide range of different distances can be obtained. Next, the screw 55 whichretains the vtubular support 5'5`is-sflackene`d off and'thisnsupport may be Arotated about'therv screwsoasto bring the outer end of the rod 4 3? into AlineV with "theinner endrso that the rod -lies Wholly parallel withY the spindle axis. If necessaryi the formerbar may be rotated through 180n fromV theposition shown in Figure 1. Y

In some cases it may be unnecessary to move th'e'spindle I3, when winding on acone-ended jpirn, the former-bar being rotatedabout the ltraverse-rod axis by a suiiicient angular extent. v In Vorder to enable'the machine to be used for cops or bobbins of difering lengths the bracket 64 is adjustable endwi'se of the bar 68Vso that'the explained, mayberad'justed. 1 Bythe present `machine itis thus possibi to Ywind cops of differentvdiameters and-different point at which vthe machine is stopped, as'labpve cone-ended pirn. -As sh'ownin the drawingsfthe 'former-bar- 36 has its profile slightly concave andit is found that 1t' isetiiipbssibiewinh such a preme te theheei'of me @op tolbbtaiaiin tight wind.
